UPRIGHT PIANO OR ORGAN CASE.

SPECIFICATION forming part of Letters Patent No. 515,926, dated March 6, 1894.

Application filed July '7, 1893. Serial No. 479.805. (No model.)

To to whom it 77mg concern:

Be it known that I, WILLIAM T. SMITH, of Baltimore, State of Maryland, have invented certain new and useful Improvements in Upright Pianos and Organs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appertains to make and use the same.

My lnvention relates to an improvement in upright pianos and organs, and more particularly to an improvement in extensible brackets and scrolls capable of being removably attached to a piano or organ whereby they may be readily changed should occasion require it at any time without the use of tools or the exercise of great skill, in order to suit this part as well as the rest of the instrument, to the taste of the purchaser.

IVi th these ends in view my invention consists in a combined bracket and leg or scroll adapted to be inserted between the key board and base of a piano, said scroll or leg capable of being turned axially and the bracket and scroll or leg having double cams at their point of contact with each other whereby when the scroll or leg is turned axially in one direction the parts will be forced away from each other.

The invention still further consists in certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims. In the accompanying drawings, Figure 1, 1s a View in side elevation of an upright piano embodying my invention. Fig. 2 is an enlarged detail, and Figs. 3 and 3 are views of the parts detached.

A represents an upright piano or organ. B the base board and G the key-board. Between the base-board and key-board the scroll or leg D and bracket E are placed in the usual manner. The bracket is provided with a socket 6 adapted to receive and fit the upper end of the scroll or legD and inside of this socket a transverse or diagonal double inclined ribf is formed, and the upper end of the scroll or leg is provided with a corresponding double inclined transverse or diagonal groove 9 adapted to receive the rib when the latter is turned in the proper position to receive it. A pair of the diametrically opposite corners 7L h of these double inclines g are preferably sloped a trifle more than the other two corners, so that the cam or wedging effect will take place at once and gradually upon turning the scroll from its normal position. By thus turning the scroll or leg the bracket is forced upward to snugly fit against the lower side of the key-board and the scroll or leg is likewise forced downward to snugly fit against the base board or in other words the bracket and scroll are forced outwardly in opposite directions to adjust them to the length of the space between the base board and key board which may slightly vary in different instruments, and also to make it possible to easily remove or apply the brackets and scrolls.

Although I have shown and described the rib as being in the bracket and the groove in the end of the scroll or leg, their positions might be transposed or they might be located at the lower end of the scroll or leg and in the base-board if desired, it not being necessary that they should be located as shown. In any event one end is provided with a pin i and the bracket with one or more pinsjj to enter holes in the bottom of the key-board.

It is evident that other slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention and hence I do not wish to limit myself to the exact construction set forth, but,

Having fully described my invention, what I claim as new, and desire to. secure by Letters Patent, is-

1. The combination with the key-board and base of an instrument,said bracket and base each having a socket therein, of a scroll or leg, the ends of which enter the sockets in the bracket and base, one end of the scroll or leg having a double cam and the corresponding socket provided with a double inclined rib adapted to engage the double cam and force the parts apart when the scroll or leg is turned axially, substantially as set forth.

2. The combination with the key-board and In testimony whereof I have signed this base-board of an instrument, of a bracket and specification in the presence of two subscrlbscroll or leg the bracket having a double iuing witnesses.

cline and the upper end of the scroll or leg WILLIAM T. SMITH. 5 provided with a double incline whereby the Witnesses:

parts are forced apart when the scroll or leg BENJ. BISSELL,

is turned, substantially as set forth. WM. H. JONES.
